Boarding pass

I sometimes wonder whether airlines and Expedia, etc., have co-marketing agreements in place with printer and cartridge vendors.  There is so much color on the damned pages for when you print out your boarding pass, so if you forget to print it black and white, you're hosed.

I know that the truly savvy fliers probably print their boarding passes at the airport so as to pawn off the printing costs onto the airline, but I like the security that comes of having the boarding pass tucked neatly away in my briefcase the night before I fly.  Perhaps I am soft.
